Engine Trouble
djhicks posted a thread earlier and sounds about like what mine is doing. I have and 08 canyon 2.9 2wd. I will start it and put into gear and it feels like its flooding out and will attempt to shut off. If I rev it up a few times it seems to ease off. It has gotten worse since the cold came it real good in the morning and at night (upstate SC). I took it to a chevy dealer when i purchased it a few months back to replace plugs and coils and they said it was a tad low on compression but not enough to be concerned about, just a few points low. Other than that it hesitates when i hit the gas and the rpms will drop.
Anyone else having similar troubles, or have heard of this? Thank you in advance.
Edit:i have not cleaned the TB of MAF yet, will do during lunch.

And to clarify, Seafoam is an internal engine cleaner not at all related to the Throttle Body or MAF Sensor.think you answered your own question sounds like the tb & maf are ditry seafoam will help as well

The throttle body has been cleaned. I will clean the MAF tonight. Is sea foam or any internal engine cleaner good to do anyways? i have 157K on the truck.
Have the O2 sensors ever been replaced??????
Willing to be they are giving the PCM slow readings......and contributing to the issues your having.
With more of these trucks climbing into the high mileage range this is a common occurrence. I replaced both of mine 2 years ago at 95k and i have never had these issues
